SPECIFITION forming part Of Letters Patent N0. 731,705, dated .Tune K23, 19013. Application `filed January 5,21903. Serial No. 137,920. (No model.) l

To' all' whom/.it may concern:

Be it, known that I, GERRIT CORNELIS `Orr- TEN, manufacturer, a subject of t-he Queen of the Netherlands, and a resident of 2O Velperweg, Oruhem, in the Kingdom of the Netherlands, have invented certain' new and usef ul Improvements in and Relating to Gras-Generating Apparatus; and I do hereby declare lthe ,p following to be a full, clear, and exact 1de- Two constructional forms of apparatus 'for carrying the invention into practice areillus-V,

trated,',by way of example, in the accompanying drawings.

Figure l is a vertical section through the apparatus, and Fig. 2a similar view ofa modification.

In the form shown in Fig. l`the apparatus consists of a reservoir A, preferably in the form of a truncated cone. Any other convenient form may, however, be adopted. This reservoirA rests upon a metallic part'B, serving as a base and also for the reception of a removable lamp C.` The reservoir A is provided laterally with a socket D, through e and is arrangedat such a height that it is imwhich the alcohol or other liquid employed is introduced for thepurpose oi' being vaporized. Thistube is closed by a screw-plug possible tolintroduce to'o large aquantity of liquid into the reservoir,1 having Vregard to the size ofthislatter. Upon the side of the reservoir "opposite to this tube Dis arranged a regulating device consisting of a tubular socket E', internally screw-threaded and projecting within the apparatus, where it preseuts three openings e, e', and c. `Outside the reservoir A the socket E receives a screw F, provided with a handle, the inner extremity of this screw serving to close to a greater or less extent the said three openings e, e', and e. l Upon these three openings are fitted three tubes. First is the tube G,throu.gh which the gas passes into the regulating appliance, which tube extends toward the upper portion or dome A of the reservoir A, where it forms a perforated crown g,through which the gas prduced in the reservoir A enters the tube G. The second tube H, also extending upward, serves for conducting the gas outside the apparatus through the pipe h, and the third tube I, extending downward, conducts a portion ofA the gas generated to supply the heating-burner m. At the lower portion of the reservoir A and `jcommunicating with thetubel is mounted a tube J, internally screw-threaded for the re ceptioin of a screw K, which is screwed into a depth'such that the opening for the passage of gas from the said tube J into the pipe Lis exactly proportioned tothe cross-sectional area of the outlet-orifice of the pipe h of the delivery-tube H for the purpose of establishing a definite relation between the quantity ofgas consumed and the quantity produced. The object is merely to regulate the aperture of the gas-passage, which should be very small, so that the flame of the heat- ,ing-burner may be of the proper dimensions,

as if'this fiame is too large the apparatus "would generate more gas than is consumed.

downward toward the lower portion of the.

reservoir A, where it is formed into a perforated crown, so as to constitutethe burner m.

Fig. 2 shows an appliance in which the regulating-socket J is omitted and replaced by a bent tube K", terminating in asmall aperture lo," the diameter of which is such that it "presents a direct relation with the outletaperture h of the pipe H.

In thedome A', Fig. l, is arranged a springseated safety-valve N. Fromwhat has been said it will, however, be readily understood that if the burner-flame is properly adjusted relatively to the volume of gas or vapor discharged, or,in other words, if the heat supplied for generating gas or vapor is regulated in accordance with the consumption of said gas or vapor, an excessive or dangerous production of such is impossible during the operation of the apparatus unless the attendant has failed to extinguish or remove the starting-lamp C, as in this case the Volume of gas or vapor produced would be much greater'than the volume of gas or vapor discharged from the generator. This valve N is omittedt in the form of apparatus represented in Fig. 2, as it is not neccssary,owing to the exact relationship established between the outlet-aperture h and the aperture tthat is to say, the aperture giving access to the burner. l

Another modification (representedin Fig. 2) is that where the pipe L opens into the pipe M, conducting to the burner. The said pipe M is enlarged, as shown at m', said enlarged portion having air-admission apertures m x, which are provided so as to permit the outer air mixing with the alcohol vapor or the like, whereby the heating power of the flame is increased.

Having thus described the constituent parts of the apparatus, l will now describe its operation. The reservoir having been supplied with liquid through the socket D, this latter is closed, the regulating device is opened by turning the handle F, and the lamp C is ignited. The heat produced by this lamp vaporizes a portion of the liquid, and the gas generated rises in the reservoir A to the dome A', whence it passes through the perforations of the crown g into the tube G, in which it descends and passes into the regulating device E, where it is divided into two parts, one of which proceeds to the burner fm., this p0rtion being reduced, owing to the regulation previously effected by means of the screw K of t-he socket J, Fig. l, or by the restricted portion formed in the bent tube K, Fig. 2. The other portion of the gas passes through the tube H outside the apparatus in the pipe h for the purpose of consumption. When once the apparatus has been started by means of the removable lamp or the like for preliminary heating, which as soon'as the gas it has caused to be generated reaches the burner m and is ignited by the said lamp is extinguished or removed, it will continue to automatically produce the desired quantity of gas until the quantity of liquid with which the apparatus has been supplied is exhausted. When this takes place, it is only necessary to replenish the apparatus, which will then continue to operate as before. If it is desired to suspend the generation of gas before the liquid to be vaporized is exhausted, it is only necessary to screw home the screw F.

This apparatus may be employed in combination with gas-consuming appliances of all kinds and with every description of burner either for heatingor illuminating the gas-supply and of obtaining any desired intensity of flame from the smallest to the largest merely by turning the handle F in one direction or the other.

The advantages tion are as follows:

First. The operation of the apparatus is not attended with any danger of' explosion, because any overproduction of gas such as could cause an explosion is impossible, owing to the equilibrium which exists between the consumption and the generation of gas, as by rotating the handle F in one direction the volume of gas supplied tothe heating-burner and the volume of gas available for consumption are reduced at one and the same timethat is to say, the flames of the heating-burner become smaller, so that naturally less gas is generated in the apparatus. In the same manner by turning the handle in the opposite direction the volume of gas passing to the heating-burnerisincreased,and consequently the volume of gas generated for consumption also, the flames of the burner in this case becoming larger and of course producing more gas in the apparatus.

Second. The combination of the regulating device within the apparatus prevents condensation and escape of gas.

Third. Owing to its simplicity, its certainty of operation, and its safety in view of the construction of the regulating device, the apparatus will be found specially adapted to the requirements of small industries and, in fact, for all purposes for which combustible gas is required.

I-Iaving now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim isl. A generator comprising a reservoir for a vaporizable liquid, a tubular socket, a gas or vapor intake contained within the reservoir and having its inlet above the normal level of liquid therein, a gas or vapor outtake, both intake and outtake connected with the aforesaid socket within the reservoir and a valve controlling both the outlet of the intake and inlet of the outtake, for the purpose set forth.

2. A generator comprising a reservoir fora vaporizable liquid, a tubular socket projecting into the reservoir, a gas or vapor intake having its inlet above the normal level of liquid in the reservoir, a gas or vapor outtake, a burner below the reservoir, said intake and outtake and said burner connected to the aforesaid socket within the reservoir and a valve in said socket controlling the outlet of the intake and the inlet to the outtake and burner, for the purposes set forth.

3. In a gas-generator, a reservoir for volatile liquid, a tubular socket, a pipe leading therefrom and terminating in a perforated crown in the gas-space of the reservoir, a gaspresented by this inven- IOO IIO

5. In a gas-generator, a reservoir for Volatile liquid, a tubular socket, avpipe leadingV therefrom tothe gas-space of the reservoir and terminating in a perforated crown, a gas supply pipe and a pipe terminating in a burner beneath the reservoir, both connected to the socket, a single Valve controlling all of said pipes and an auxiliary valve in the burnerpipe to proportion the gas supplied to the burner to that generated, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
